Problems with screen resolution using Win 10 IoT and R Pi Official 7-inch touch screen

Question

The official Raspberry Pi 7 "touchscreen ( https://www.raspberrypi.org/products/raspberry-pi-touch-display/ ) works fine with Windows 10 Core IoT Core running on my Raspberry Pi 2 B, as support was added back to the Insider preview (display and touch are functional), except for the screen resolution, which is almost correct, but everything on the screen looks slightly stretched horizontally, which gives UI applications a cheap feel. The most noticeable are the circular shapes that stretched horizontally into an ellipse shape.

I came across the values ​​in the config.txt file, which claims to use 800x480 , but no changes have any effect on the screen. Is there a way to make the resolution more suitable for 800x480 screen sizes? Below is config.txt . Look carefully; I use the custom permission that everyone offers. What I mean is a slight stretching of the screen, and not a completely wrong resolution.

This seems to be a hardware issue. There are several reports that the aspect ratio of this device is turned off by about 10%.
